T all whom t nelly concern:

Be it known that I, FRANK SoLEY, a citizen of the United States,residing in Philadelphia, Pennsylvania, have invented certainImprovements invPadlocks, of which the following is a specification.

Theobjects of myinvention are to construct 'in a cheap and simple form apadlock in Figure 1 is a view of a padlock constructed in accordancewith my invention, some of the transverse pins and the key-barrel andkey being shown in section and the parts being shown lin the lockedposition. Fig. 2 is a similar View showing the parts in Ythe unlockedposition. Fig. 3 is a transverse section of thelock,with some of theinternal parts shown in elevation. Fig. 4 isa perspective view of one ofthe elements of the lock; and Fig. 5 is a View similar to Fig. 1, butillustrating a modiied construction of the lock.

The casing 1 of the lock may be of any desired shape and made in anysuitable way, this Vforming no part of my invention.

The shackle 2 is hung, as usual, to a transverse pin 3 and in the lockshown in Figs. 1

suitable pivot-pin 7 in the lock-casing, the tail 8 of said dog when thelock is closed bearing upon the top of a sliding rplate 9, which isslotted at the ends for the reception of suit-f able transverse pins and11, upon which said plateV 9 is thus mounted and by which is guided inits movement.

Around the pin 10 is coiled a spring 12, one end of this spring actingupon a pin 13 on the plate 9, so as to tend to constantly move the sameforward, or to the position shown in Fig. 1, the other end of the spring12 acting upon a pin 14, projecting from the heel 2n of the shackle, soas to open the lock y as soon the hooked end of the shackle is releasedfrom engagement with the hook of Y Hung to the pin 11 are a series oftumblers l5, each acted upon by a spring 16, tending to depress it to anextent limited by contact of a lug 17 on the free end of the tumblerwith a stump 18, projecting from the face of the plate 9, and in eachtumbler is formed a notch 19, so that when the tumblers are raised bymeans of a properly-bitted key the notches of all of the tumblers willbe brought into line with the stump 18, and the plate 9, carrying thelatter, can be caused to move rearwardly, or to the position shown inFig. 2, by reason of the action of a portion of the key upon a shoulder20 on said plate. When the lockis closed, the shackle 2 is doublyllocked, first, by reason of the engagement of the hook 4 of the shacklewith the hook 5 of.

the dog 6, and, secondly, by reason of the engagement of the heelportion 2a of the shackle with the tail 8 of said dog, as shown in Fig.1, softhat the iirm and secure retention of the shackleain the lockedposition is insured. In `the upper portion of the plate 9, however, is

a recess 21, and when said plate 9 has been retracted,by means of thekey, to the position shown in Fig. 2 the tail 8 of the dog 6 can enterthis recess, thus permitting the with Adrawal of the hook 5 of the dogfrom engagement with the hook 4 of the shackle and removing the tail 8from the path of the heel 2a of the shackle, so that the latter is freeto be swung open under the action of the spring 12, as shown in Fig. 2.When the dog is in been adjusted by the key, while movement of the dogis prevented by contact of the tail v8 of the same with the heel of theshackle.

so that the latter is again moved to the posi IOO tion shown in Fig. 1,the heel of the shackle having, as said shackle is closed, been movedout of the path of the tail S of the dog, so that the restoration of thelatter to the position shown in Fig. 1 is not interfered with. As thetail of the dog is lifted from the recess 21 of the plate 9 the latteris free to move forward by the action of the spring 12, thus carryingthe stump 1S out of the notches of the tumblers and permitting thelatter to be depressed bythe action of their springs 1G, and at the sametime that portion of the plate 9 in the rear of the recess 21 is carriedunder the tail S of the dog (3, so as to again retain the latter andprevent the release of the shackle until the parts have again beenproperly moved by the action of the key.

In the modified form of lock shown in Fig. 5 the hook 4 upon the shackleand the hook 5 upon the dog have been dispensed With, a spring 24serving to move the dog from the locking position shown in Fig. 1 to theunlocking position shown in Fig. 2 and the shackle being locked byengagement of the heel of the same with the tail of the dog. The finger22 may be dispensed with, if desired, and the dog moved from theunlocking position, Fig. 2, to the locking position, Fig. 1, by theaction of the beveled rearend of the recess 21 of the plate fl, or whenthe hooked dog is used this movement of the same may be effected by aspring.

Having thus described my invention, I claim and desire to secure byLetters Patent- 1. The combination in a padlock,of a swinging shacklehaving a projecting heel, a pivoted locking-dog having a tail forengagement with said heel to retain the shackle in the closed position,means for moving said dog from the locking position to the unlockingposition and vice versa, a sliding plate for retaining thelocking-doginposition When the lock is closed, and tumblers serving to hold saidlocking-plate in its locking position until actuated by a proper key,substantially as specified.

2. The combination in a padlock,of a swinging shackle having a hookednose, a lockingdog having a hook for engagement with said hooked nose ofthe shackle, means for mov- .ing said dog from the unlocked to thelocked position, a sliding plate for holding said locking-dog inposition when the lock is closed, and tumblers serving to hold saidlockingplate in its locking position until actuated by a proper key,substantially as specified.

3. The combination in a padlock,ofa swinging shackle having a hookednose and a projecting heel, a pivoted locking-dog having a hook forengaging with said hooked nose of the shackle, and a tail for engagingwith and locking the heel of the shackle when the latter is closed,means for moving the dog from the unlocking to the locking position, asliding plate for retaining the locking-dog in position when the lock isclosed, and tumblers serving to hold said locking-plate in its lockingposition until actuated by a proper key, substantially as specified.

4. The combination in a padlock,ofa swinging shackle having a projectingheel, a pivoted locking-dog having a finger to be struck by the nose ofthe shackle as the latter is closed so as to move the dog from theunlocking to the locking position, and a tail for engaging with theprojecting heel of the shackle and holding the latterin the closedposition, means for moving the dog from the locking to the unlockingposition, a sliding plate for retaining the locking-dog in position whenthe lock is closed, and tumblers serving to hold said locking-plate inits locking position until actuated by a proper key, substantially asspecified.

5. The combination in a padlock, of a swinging shackle having a hookednose and projecting heel, a dog having a hook for engaging said hookednose of the shackle, a finger for being struck by the nose of theshackle as the latter is closed so as to move the dog from the unlockingto the locking position, and a tail for engaging with the projectingheel of the shackle to hold the same in the closed position, a slidingplate for retaining the dog in locking position when the lock is closed,and tumblers serving to hold said locking-plate in its locking positionuntil actuated by a proper key, substantially as specified.

G. The combination in a padlock,of a swinging shackle having a hookednose, a pivoted locking-dog having a hook for engaging thel hooked noseof the shackle, and a finger for being struck by said nose as theshackle is closed so as to move the dog from the unlocking to thelocking position, a sliding plate for retaining the dog in lockingposition when the lock is closed, and tumblers serving to hold saidlocking-plate in its lookin g position until actuated by a properkey,substantially as specified.

7. The combination in a padlock,of a swinging shackle, a pivotedlocking-dog adapted to engage with said shackle to hold it in the closedposition, a sliding plate which retains the dog in locking position whenthe lock is closed, but which has a recess for receiving the tail of thedog when the lock is open, notched tumblers adapted to be adjusted by akey, and a projection upon the slidingplate for engaging with thenotches of the tumblers when the latter have been so adjusted, the tailof the dog, when the plate is retracted, occupying the recess in saidplate and holding the same in the retracted position, substantially asspecified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
